None of those activities is a waste of time. Cleaning for obvious reasons, but playing MMOs for less obvious, yet equally important ones.
I play MMOs because they allow me to closely interact, in real time, with people around the world. I gravitate towards global guilds/clans/communities which feature people coming from various locations and with various backgrounds. I learned a lot about other countries and other people simply by playing together.

I listen to podcasts while doing chores, but I could listen to podcasts while I play my favorite MMO just as well.

Dune was pretty good at the time. So were the movies derived from Arthur C Clarke's work.
I'm okay with adaptation, what I'm not okay is removing the fucking main character of the book from the movie (e.g. Riverworld which was a HORRIBLE movie).

There are so many great, GREAT books which deserve great, GREAT movies: Tuf Voyaging, A Fire Upon The Deep, Spin (by Robert Charles Wilson), Camouflage (which is really not difficult to put on screen).
If you really want to go crazy, Greg Egan's books are the thing. I'd be very much curious to see Schild's Ladder as a movie.
As for the sex-laden tendency of HBO as of late, they should simply take "Tous vers l'extase" written by Philippe Curval and be done with it - they don't even have to modify it :)

HBO = Heavy Boobs Office?

Cmdr. Riker-like, not more.
If you look at Star Trek:TNG Series 1-2, Riker was quite a ladies' man, but the way it was put on screen was great: developed his character very well without turning into softporn.

For her "meat"?

Only prison (jail) time is not (in theory) about making you feel miserable. One is not helped by being made miserable.
Prison time is (in theory) intended to put someone in a controlled environment where he could redeem by performing various activities while at the same time preventing said individual from continuing on the wrong path. The fact that it, in practice, became something very different is another story.

Would a vegan eat an animal who dies of old age? Or in an accident? How about roadkill?
Cicadas, for example. They have a very short life span (outside of the tree trunks) and are edible immediately after death (if cooked right).

I think we're avoiding the correct question.
When you are sent to jail, you lose some rights. Would the ability to eat specific types of food (or not eat them thereof) belong to the rights you lose or not?
If it does, then this is a non-issue. If it doesn't, then we have a problem.

That's if you have shit to share. I don't. My account exists there because other people have shit to share and I am perusing it. That is, a few close friends and relatives who live abroad. Handpicked people.

I have printed porn images on HP printers around the world using just Google :)

They could be made simpler by designing and creating applications, UIs and features which "do one thing but do it well".
There's little incentive to do so, though, although I have to say that smartphones got there already, more or less.

My childhood house had this:
- Rain falling on the house roof was channeled into a subterranean pool.
- Water stored there was used to water the garden and wash out the shit from the outside loo.

I wonder whether building a second subterranean room below the first would do the trick. The rooms should be quite large (7x7x5 meters each!) to store up to 195 cubic meters of water, but if you have a large enough courtyard you should be able to make two 10x10x2 meter rooms on top of each other, separated by a strong ceiling. You could bring the water back to the top room by using energy coming from a small wind-operated turbine.

This is just theory, throw rocks at will.

Europe doesn't have much locally drillable oil resources, as for fracking, it's a sensitive subject which splits population right in half.
